Failed to read data from the disk

This error typically points to a failing drive.

#1) What kind of hard drive is in your Acer - spinning, SSD or EMMC flash?

If it's a spinning drive, I'd still error on the side that it is failing.  You may want to check your Windows System Logs to see if any other hard drive errors or warnings show up there too.  Also, see if Acer has a hard drive diagnostic utility of their own.  I couldn't find one on a U.S. site, but this link from Acer UK has one:

Seagate Seatools is another good hard drive tester and should work on any brand hard drive - so should Western Digitals Hard Drive Diagnostic tools (the Windows GUI versions of both are universal, but the DOS versions are reported by some to only work on the specific brand).  There are other free tools tool, most of which will be a bit more thorough than CHKDSK (which is a good starting point, but not definitive by itself).

#2) Are you getting this error through Acronis in Windows and with offline Acronis bootable media, or have you not tested both?  Try both and see if they have the same results.  You might find that one is able to make an image - offline recoverable media has the advantage that Windows is not in use so VSS is not needed and it doesn't have to compete with resources from Windows or other loaded applications which may be causing issues (like Virus scanning or Security software). 

#3) I can't recommend a competing software prodcut in this forum, but there are other free tools that are capable of doing a full disk image backup when restoring to the same hardware... if you want univerals retore "like" options, those usually come at a price.  Google "free disk imaging software" and the mirroring software I would use as my second choice should be at the top of the list.  Although I think acronis is great and has worked well for me, if I couldn't get it to backup my critical data, I wouldn't hesitate to give another software product a chance to see if it can image the disk (make sure you test and attempt to recover your data to another drive too though to be doubly sure if it does say it's successful).  

#4) I have had some luck cloning failing disks with hardware duplicators (roughly $60 from the big "A" website or just Google USB 3.0 Hard drive duplicator) when software solutions couldn't get past bad sectors/blocks.  Doesn't always work, but it's been pretty reliable except when a hard disk is completely FUBAR.  If the dock can't do a hardware clone, you definitely know you have a bad disk, and if it can, well at least you have a good copy in the event the disk is on its way out.  

1) It's a spinning hard drive.

2) I get this error through both in Acronis in Windows and through the offline Ancronis bootable media.

I'll try to see if the hard drive is failing. If it is, then I could just try buying a new internal hard drive. But I care more about saving my data. And if I still get those errors, is it okay if I just ignore all of them?

Ned, I would also recommend running CHKDSK /F /R against your source disk drive which Acronis reports as Drive 1 in the error message (Acronis count from 1 for drives versus Windows which counts from 0).

If you ignore bad sectors on your drive then you risk the backup image you make being unusable later.

I would recommend copying any vital data (user documents, pictures etc) to a separate drive or making an Acronis Files & Folders backup of the same and hope that none of the data occupies the bad sector being reported.

Thanks for letting me known about it being unusable if I ignore the bad sectors. Yeah, I guess I could just copy the files and folders instead of the whole disk. Now I ran that utility provided by Acer and it completed the thorough scan and said that it had bad sectors on the disk. My options were to either repair or cancel. When I clicked Repair, it warned me that trying to repair the bad sectors will result in a loss of data. I didn't want that to happen, so I pressed cancel. I will run that chkdsk utility, but I have no idea what it will do to my drive. Now I am thinking about just buying a new 1 TB hard drive and reinstalling Windows on that so hopefully I won't get anymore issues that I'm experiencing. I don't wanna go into full detail about the issues I have.

Ned, CHKDSK should not cause any further damage to your drive by running it - it is operating at an OS level and verifying that the NTFS filesystem is working correctly - it will give you a report when it finishes to show what problems are found and actions taken.  If you miss the report, it can also be found in the Windows Event logs.

If it were me, I'd still take the backup with the ignore bad sectors - better to have something to try to fall back on than nothing.  chkdsk is normally not destructive, but I have seen it "repair" data on drivces in RAID 5 that did fix the problem, but corrupted the actual data in the process.  i have not seen this behavior on a standard single drive instance though and usually don't think twice about running chkdsk.  But, if you want a little extra security and can complete a backup with the "ignore bad sectors" option, that gives you some hope for reovery if you get to the point where you need to be able to do so. 

Shouldn't it just be CHKDSK /R?. I've heard that /r does everything that /f does including what /r does.

CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I] [/C] [/L[:size]] [/B] [/scan] [/spotfix]

  volume              Specifies the drive letter (followed by a colon),
                      mount point, or volume name.
  filename            FAT/FAT32 only: Specifies the files to check for
                      fragmentation.
  /F                  Fixes errors on the disk.
  /V                  On FAT/FAT32: Displays the full path and name of every
                      file on the disk.
                      On NTFS: Displays cleanup messages if any.
  /R                  Locates bad sectors and recovers readable information
                      (implies /F, when /scan not specified).
  /L:size             NTFS only:  Changes the log file size to the specified
                      number of kilobytes.  If size is not specified, displays
                      current size.
  /X                  Forces the volume to dismount first if necessary.
                      All opened handles to the volume would then be invalid
                      (implies /F).
  /I                  NTFS only: Performs a less vigorous check of index
                      entries.
  /C                  NTFS only: Skips checking of cycles within the folder
                      structure.
  /B                  NTFS only: Re-evaluates bad clusters on the volume
                      (implies /R)
  /scan               NTFS only: Runs a online scan on the volume
  /forceofflinefix    NTFS only: (Must be used with "/scan")
                      Bypass all online repair; all defects found
                      are queued for offline repair (i.e. "chkdsk /spotfix").
  /perf               NTFS only: (Must be used with "/scan")
                      Uses more system resources to complete a scan as fast as
                      possible. This may have a negative performance impact on
                      other tasks running on the system.
  /spotfix            NTFS only: Runs spot fixing on the volume
  /sdcleanup          NTFS only: Garbage collect unneeded security descriptor
                      data (implies /F).
  /offlinescanandfix  Runs an offline scan and fix on the volume.
  /freeorphanedchains FAT/FAT32/exFAT only: Frees any orphaned cluster chains
                      instead of recovering their contents.
  /markclean          FAT/FAT32/exFAT only: Marks the volume clean if no
                      corruption was detected, even if /F was not specified.

The /I or /C switch reduces the amount of time required to run Chkdsk by
skipping certain checks of the volume.
